Ramdisks and hard drives as cache devicesRamdisks and hard drives as cache devicesPosted Jul 8, 2010 23:19 UTC (Thu) by koverstreet (subscriber, #4296)In reply to: Ramdisks and hard drives as cache devices by etienne Parent article: Bcache: Caching beyond just RAM
Bootloaders are a special situation - the most practical thing to do would be to just not enable write behind caching for /boot. For everything else, sync happens when you switch off write behind caching, and sync without switching it off doesn't really make any sense, the cached device is going to be inconsistent as long as write behind caching is on.
